| 摘 要： | 用Ｈａｍｍｅｔｔ指示剂法和红外光谱法研究了苯胺气相甲基化催化剂的表面酸性及其对催化性能的影响。结果表明，表面酸量和酸强度较小的催化剂，反应性能较好。苯胺的气相甲基化反应与酸中心的类型无关。另外，对在氧化铝和分子筛上苯胺甲基化的反应机理进行了探讨。

| Abstract: | The surface acidic property of aniline methylation catalysts and its influence on their catalytic activities has been studied using Hammett indicator method and FT-IR technique. The results show that the catalyst with smaller acid strength and smaller amount will be better and the methylation of aniline has no relationship with the types of acid sites.The mechanisms of methylation of aniline over alumina and HZSM-5 zeolite have also been discussed respectively. |
